ColorBowl: Hair Formulas

ColorBowl is a local-first hair formula book for professional colorists and stylists.

Use ColorBowl to keep user-entered client color notes, formula visits, zone-level formulas, product usage, product cost references, service notes, and margin estimates organized on your Android device.

ColorBowl is built for recordkeeping. It helps you remember what you used, where you used it, and what to review before the next visit.

Features:
- Record client color-history notes locally.
- Track formula visits with before, after, and next-visit notes.
- Add formula zones such as roots, mids, ends, toner, gloss, highlights, or custom zones.
- Save ingredients with product name, shade code, grams, developer volume, developer amount, and notes.
- Maintain a local product library with user-entered unit cost data.
- Estimate service cost and gross margin in Cost Lab.
- Review formula history in timeline and detail views.

ColorBowl does not generate professional formulas, provide chemical safety advice, diagnose allergies, provide medical advice, or guarantee color results. Always use your own professional judgment and follow product manufacturer instructions.
